Increased levels of chaperones increase heat resistance of bacteria by
A) destroying damaged proteins so the amino acids can be recycled.
B) refolding proteins damaged by heat so they function again.
C) secreting damaged proteins into the periplasm.
D) labeling damaged proteins for destruction by clp proteases.
E) adding N-formylmethionine to damaged proteins.

Question

Quizplus · Accepted Answer

Increased levels of chaperones help refold proteins that have been damaged by heat, allowing them to function again and increasing the heat resistance of the bacteria. Option A is incorrect because chaperones do not destroy damaged proteins, but rather assist in their refolding. Option C is incorrect because chaperones do not secrete damaged proteins into the periplasm. Option D is incorrect because labeling damaged proteins for destruction by clp proteases is not a function of chaperones. Option E is incorrect because adding N-formylmethionine to damaged proteins is not a function of chaperones.
